1 Claim. (01. 58-58) This invention relates to horologioal instrumeshedwith the gear l4 and mounted upon a ments and it has particular relationto a novel suitable shaft, not shown, is a gear 18 having wrist watchprovided with a series of dials driven twenty-four teeth. A gear 19having seven teeth by a conventional watch mechanismfor indiis mountedupon this same shaft and is eneating not only the time of the day butalso the meshed with a gear 2E having 56 teeth and 5 day of the week,the day of the month, the mounted upon a shaft 2! which carries at itsmonth and the lunar conditions. upper end an hour indicating dial 22.Below this The primary object of this invention is the dial and mountedupon the shaft 21 is a gear provision of an astronomical watch whereinnov- 23 having four teeth and below the gear 23 and el means is providedfor driving a plurality of also mounted upon the shaft 2| is a gear 2410 indicia bearing dials from a single conventional having a singletooth. Another gear 25 having a watch mechanism. single tooth is mountedupon the shaft 2! below Another object of the invention is the provithegear 24. sion of a device of the character described where- A gear 26having sixteen teeth is carried upon 5 in the dials are positivelydriven and the entire a suitable shaft 21 and meshes with the gear 23mechanism is capable of enclosure within a case and also with a gear 28having twenty-eight teeth. no larger than the ordinary wrist watch. Tothe upper side of the gear 28 is fastened a day A further object of theinvention is the proviof the week indicating dial 3B. The gear 28 hassion in a Wrist watch of a novel arrangement of sleeve 3! revolublymounted upon the Shaft go adja dials in pping relation for coni 3. Thisshaft i3 also carries a gear 32 having selvatien Of Space and a novelarrangement of twenty-eight teeth and having a sleeve extendindicia onthe dials whereby the indicia on ading t h t Sleeve 31 and having th l rlaeent a even though the dials ap, y condition indicating dial connectedthereto.

It will alsobe, seen that whenever the particular month has less than thirty-onedays, the dial 38 and the dial 37 may be manually adjusted by means ofthe manual adjusting stem ii. This stem 4! has a gear 45 which engagesgear 83 for resetting dial 38.

The lunar indicating dial 227 bears a representation of the moon 53 uponits upper surface and adjacent the periphery of the dial, whichrepresentation is so placed as to show literally the various stages ofthe moon by means of an irregularly shaped opening 5i cut in the face ofthe clock.

Although but one form of the invention has been illustrated, and thatform has been described in detail, it will be apparent to those skilledin the art that the invention is not so limited but that variousmodifications may be made therein without departing from the spirit ofthe invention or the scope of the appended claim.

' I claim: v

An astronomical watch comprising a housing having sight openings in itsface, one of the openings being of a predetermined irregular shape, aplurality of dials rotatably mounted within the housing for coaction onewith each of the openings, said dials consisting of minute indicatingdial, an hour indicating dial, a day-of-the- Week indicating dial, aday-of-the-month indicating dial, a month indicating dial and a lunarcondition indicating dial bearing a representation of the moon andadapted to coact with the irregular shaped opening in the face toindicate the instant 'lunar condition, a conventional watch mechanismdisposed within the housing, a train of gears interconnecting the dialsand the watch mechanism whereby the various dials are'operated atpredetermined speeds, one of the gears having afiixed to it the day ofthe month indicating dial, a stem protruding at one side of the easingfor winding the watch mechanism and a second stem protruding through theopposite side of the casing and carrying a gear within the casing forengaging at will the gear carrying the day-of-the-month-indicating dialwhereby it may be reset.
